Try booting Ubuntu without UEFI or Secure Boot. After that, you should be able to install it. If not, boot to the live CD (Try Ubuntu without installing) instead and install from there. Once you have installed, you may not be able to boot Ubuntu. Run this code from a live CD:

sudo apt-get install boot-repair
sudo boot-repair

Choose the recommended repair and follow the instructions boot-repair gives you, then reboot. You should be able to boot into Ubuntu.

I had the same problem when I was installing the Ubuntu 13.04 at my Inspiron 14z.
You've to change the configuration on BIOS. Enter UEFI to LEGACY and change the boot device that you want to start in your laptop.
